经过6年的品种筛选及大面积栽培结果表明:从巴西(或威廉斯)农科1号、台蕉2号,再到台蕉218、台蕉190(抗枯5号),在连续的单一栽培种植过程中无一例外地出现了抗病性逐渐下降、香蕉枯萎病发病率随连作年限的增加而逐年增加的现象。目前,具有一定抗病性的新品种南天黄及粤科在连作栽培情况下,其抗病性能持续多长的时间还需要进一步的观察。对于新开垦的蕉园,枯萎病综合防控技术建议如下:1.种苗:禁止从有病区引进杯苗,
After six years of variety selection and large-area cultivation, the results showed that from Brazil (or Williams) Agricultural Science No. 1, Taijiao No. 2, to Taijiao 218, Taijiao 190 (Kangqu 5) During the cultivation and planting process, the disease resistance gradually decreased and the incidence of banana wilt disease increased year by year with the increasing number of consecutive years. At present, a new variety with a certain disease resistance Nantian and Yue Branch in the case of continuous cultivation, the duration of disease resistance will continue to need further observation. For the newly reclaimed banana plant, the comprehensive prevention and control technology for fusarium wilt is as follows: 1. Seedlings: banning the introduction of cup seedlings from the ward,
